GOSHEN — Day four of the first-degree murder trial in the slayings of Gerald and Francis Piscopo began Wednesday morning in Orange County Court with graphic testimony from Orange County

Medical Examiner Charles Catanese.

Gerald Piscopo was shot four times - in the left shoulder, right shoulder, through the neck and in the top of the head. His uncle, Francis Piscopo, was shot twice - in the right side of his neck and in the back of his head.

Catanese was testifying at the trial of Victor Koltun, the Brooklyn rabbi charged with masterminding the Piscopos’ Nov. 4, 2010 deaths.

Two ex-cons who admitted to being the gunman and the lookout are serving prison time for conspiracy.

Under questioning from Assistant District Attorney Steven Goldberg, Catanese testified that both of Francis Piscopo’s wounds were close-range, with the gun no more than two to three inches away. The shot to the back of his neck exited through his mouth, Catanese said, fracturing his thyroid bone, jaw and teeth and damaging his tongue and lip. That wound was survivable, he said; the head wound was not.

Catanese said Gerald Piscopo was shot in the left shoulder and the left side of the neck. The bullet to his neck traveled through the neck left to right in a downward trajectory, damaging both of his carotid arteries; the bullet exited his neck and re-entered his right shoulder, stopping in his armpit. Gerald Piscopo was shot in the top of his right shoulder. The fourth wound was a contact wound to the top rear of Gerald Piscopo’s head.

“The end of the barrel of the gun was pressed tightly against the back of his head,” Catanese testified.

The medical examiner said Gerald Piscopo could have been conscious for 20 seconds or more after the neck wound, but it wasn’t survivable. The head would have rendered him immediately unconscious, with death following quickly.

The trial will resume Wednesday afternoon, with cross examination of Catanese by Koltun’s lawyer, Glen Plotsky.
